In this paper, we aim at the study on multi-mode transceiver based on software defined radio(SDR). Multi-rate signal processing and polyphase filtering technique are both applied in the design and implementation of the transceiver. Simplified FFT butterfly algorithm has been employed in the polyphase filter design as well. Simulation results illustrate that BER performance can be improved by adopting the SDR proposed in this paper. Especially, it has obvious advantages at low SNR. Meanwhile, improved filter design scheme has much more predominant in-band and out-ofband performance.
